My inventionA` relates to posts constructed? for location in the ground and serving as supports, attaching means, anchors, etc. The post of my invention employs a bar formed with side walls which are collapsed at the lowerend of the bar, `andan anchoring body moulded about said bar Where collapse The side walls of the bar, where collapsed,

cooperate with each other to prevent the withdrawal of the bar from the anchoring element. y

In the preferred embodiment of the invention the bar is in the form of an angle iron whose sides or Walls, where collapsed,

are shaped into intermeshing, sinuous Iformations. The s'inuous formations in the walls or sides of the angle iron prevent the l langle iron from beingwithdrawn from the moulded anchoring element, the walls engaging each other to prevent them from be-l ing movable toward each other by the action of the surrounding moulded material, which is preferably concrete, when the bar is stressed.

The invention will .be more yfully explained in connection with the accompanying drawing'ln which Fig. ,l lllustrates the preferred embodiment thereof as employed in connection with ya tower formed of structural iron, such asused, for example, in I supporting wind mills and high tension current transmission wires; Fig. 2 isa longitudinal sectional View showing the angle iron of the post in elevation, theconcrete being removed from the space between the side walls of the angle iron, for clearance; Fig. 3 is a perspective View illustrating the collapsed formation of the an le iron, the upper portion of the angle' iron eing brol'ie away; Fig. 4 is a view of the lower portion of the structure shown in Fig. 2 on lined-4 of Fig. 2; and Fig.' 5 is a sectional View on line of Fig. 2.

The tower structure shown in Fig. 1 has as' many underlying posts as it has sides,

` each inclined corner rail l of the tower being riveted at its lower or ground end with the upper end of a bar lwhich, as illustrated, is

,inclusive of two angularly related side Walls 2 to constitute au angle iron. Each angle iron has vits sides or walls 3 collapsed to rosa. -v V Application filed June 27, 1925'.y Serial No. 40,024.

shaped into interlneShii or walls 2 beino' l 'hegangle irons are inse 5B iforinations 3.

in suitably prepared holes in the ground'gl" whereafter concrete is ypoured into the holes in the ground to surround the an le irons therein, particularly the portions o the afm-l gie irons where their lsides are collapsed. 4G0 The bodyV of' concrete surrounding the 'colf lapsed portion of Ieachangle iron is enlar ed at the lower end of the post intoa ba 4,

the concrete body being reduced above'the ball 4 to forma stem 5 that surrounds the 65 upper parts of the collapsed ortions of the angle iron and'also the unco lapsed balance of the angle iron. ""e enlargement 4 serves to prevent the withdrawal of the post, 'as a v Whole, from the ground. The sinuous for- -10 mations 3, lby engagingeach other, are pre-Vz j jvented from coming any closerltogether so that the angle iron cannot readily bewithdrawn from the anchoring elementv surrounding it.

The corner rails 41 of the tower are dei sirably of angle iron with the corners outer A most'. Consequently the corners of the angleirons'in the posts'are outermost, these angle irons and the inclined corner rails 1 of the 80 y tower being in nestingiengagement'. With this construction the channels in the angle irons 'face downwardly somewhat, and there-v fore cannot serve to yconduct the concrete as this concrete is inserted in the post holes.v :5,

The concrete vshould be packed, however," intothe holes in. a manner' to, fill the chan- ,I mills in the angle irons as compactly as si e.

packed `into the channels in the an l @on vnrk:

as desirable in the construction of t If the concrete could be as tighiilsy:` i

ous'posts, the Walls of the an le irons nxigliii:l l'

be prevented from collapsing y the concrte" interposed therebetween; Asthis result'cannot, iowever, be assured, I have resorted tolli the collapsing of the angle iron sides as set'd forth, whereby these sides reinforce each other and prevent their furthercollapsng to guard against the withdrawalof the angle irons from the concrete anchoring elements.

In actual practice the post holes are formed" by means of earth angers, these holes being enlarged at their lower ends by explosion in a mannerwell known, the Ground where gather at the lower ond of the angleiron, the the post holes are thus forme acting-as 'a 105A collapsed portions of the angle iron sides to serve as cores inthe mould and about which cores the concrete is poured and packed. .v

Having 'thus described my invention, I claim: l

1. A ground anchorage for a tower or similar structure comprising a length of angle iron adapted to be inserted in a hole in the ground, the upper end portion of said angle iron being adapted for connection with the tower or similar structure and being or' normal conguration with the side walls thereof disposed at or substantially at right angles to one another to. resist bending strains imposed thereon by the tower, the lower end portion ot' said angle iron having the side walls thereof collapsed together, and a mass of cementitious material surrounding the collapsed lower end portion of said angle iron.

2. A ground aiijchorage for av tower or similar structure comprising a length of angle iron adapted to be inserted in'ahole in the ground, the upper end portion of said angle iron being adapted for connection with the tower or similar structure and being of norlnal configuration with the sidel walls l thereof disposed at or substantially at right lower end angles to one another to resist bending strains imposed thereon by the tower, the portion of said angle iron having the side walls thereof collapsed together, and' a mass of cementitous material surrounding the collapsed lower end portion needed; n

ot' said angle iron, the said collapsed Side walls of the lower end portion of said angle iron being provided with intermeshing siiiuous formations. i

3. A ground anchorage for a tower 'or similar structure comprising a length of angle iron adapted to be inserted in a hole in the ground, the upper end portion of said angle iron being adapted for connection with the tower or similar structure and being` of normal conliguration with the side walls thereof' disposed at or substantially at right angles to one another to resist bending strains imposed thereon by thetower, the.

lower endportion of said angle iron having the side walls thereof collapsed together,

lateral p oiections on the collapsed lower end pori: -ii of said angle iron, and a mass olE cemeiilitious material surrounding the collapsed lower end portion of said angle 4. A post including a bar formed with side walls which are collapsed 4together at the lower end oi the b'ar and shaped where collapsed into intermesliing sinuous formations, and an anchoringbody moulded about said bar where collapsed and uncollapsed, this anchoring' body being enlarged where it surroundsl the collapsed portion of the bar.

In witness whereof, I hereunto subscribe my name. v
